The CBG01A Keypad is a compact and versatile operating and display unit designed for use with SEW-EURODRIVE inverters, including MOVITRAC® basic and MOVITRAC® advanced series. It provides a user-friendly interface for monitoring, parameterizing, and controlling drive trains, making it an essential tool for commissioning, maintenance, and manual operation.
Function Description
The CBG01A Keypad serves as a direct interface to the inverter, allowing users to perform a variety of tasks without the need for external engineering software in many cases. Its core functions include:
- Inverter Status Display: The keypad provides real-time information about the inverter's operational status, including current speed, current, DC link voltage, FCB number, and fault numbers. This allows for quick diagnostics and monitoring of the drive's performance.
- Parameter Access and Modification: Users can access and change a wide range of inverter parameters via an index-based system. This includes fixed setpoints for acceleration, deceleration, and speed, as well as various device properties, diagnostic values, and input/output settings. The keypad supports both decimal and hexadecimal value entry, with clear indications for hexadecimal displays.
- Startup Functionality: The CBG01A facilitates the startup of asynchronous and synchronous motors, including brake and encoder startup. It allows for the entry of nominal motor data (voltage, current, frequency, power, power factor, and speed) according to the motor's nameplate, which is crucial for optimal control performance. However, it's important to note that if startup has already been performed with MOVISUITE® engineering software or another keypad (CBG11A or CBG21A), the CBG01A keypad might be blocked from accessing that specific drive train.
- Data Management: The keypad supports uploading ("store") and downloading ("recall") of parameter sets to and from the inverter. This feature is invaluable for backing up configurations, transferring settings between similar drives, and restoring previous operational states. It also includes error messages for data transfer failures or incompatibilities between data sets and the inverter.
- Manual Operation: The CBG01A enables manual control of the motor, allowing users to enable/revoke the inverter, increase/decrease speed, and change the direction of rotation. This mode is particularly useful for testing and troubleshooting. A safety warning is provided regarding unexpected startup when using manual mode, emphasizing the need to ensure no persons are in the area of rotating parts before activation.
- Display of Device States and Errors: Beyond normal operation, the keypad displays various device states during boot processes, initialization, and error conditions. This includes messages for energy-saving mode, DC link voltage missing, module bus not ready, startup state, STO active, unsuccessful synchronization, encoder evaluation not ready, motor management not ready, internal device supply incomplete, and power section not ready. For errors, it shows main faults and subfaults, return codes of the application, keypad connection errors, data stream connection errors, and AppService errors, providing detailed information for troubleshooting.
Important Technical Specifications

Usage Features
- Intuitive Navigation: The keypad features navigation keys (up, down, left, right), an OK button for confirmation, and an ESC button for exiting menus. Pictograms on the display guide the user through different main menu levels, making navigation straightforward.
- Multi-Digit Number Entry: The keypad supports entering multi-digit numbers by selecting individual digits and adjusting their values using the up/down arrow keys.
- Clear Display of Values: The 7-segment display shows status, values, and parameters, often switching between different displays every 2 seconds to provide comprehensive information. Hexadecimal values are displayed with a leading "H" (e.g., "0H3E8").
- Safety Notes Integration: The manual emphasizes safety through structured safety notes, signal words (DANGER, WARNING, CAUTION, NOTICE, INFORMATION), and hazard symbols (general hazard, warning of automatic restart). These are integrated into the documentation to ensure users are aware of potential risks and preventive measures.
- Parameter Indexing: Parameters are accessed via an index system, with detailed tables in the manual providing the index, possible values, and their meanings. This allows for precise configuration of the inverter.
- Bit Pointer Functionality: The keypad supports bit pointers, enabling one parameter's value to refer to another, which is useful for advanced configurations, such as assigning a limit switch to a digital input.
Maintenance Features
- Diagnostics and Error Display: The comprehensive error display system, including main faults, subfaults, and various return codes, aids significantly in diagnosing issues. Messages like "Keypad connection error" or "Data stream connection error" provide immediate guidance for troubleshooting connectivity problems.
- Parameter Set Management: The ability to store and recall parameter sets is a crucial maintenance feature. It allows for quick restoration of known good configurations after a fault or during device replacement, minimizing downtime.
- Information on Device States: Displays during boot-up and initialization provide insights into the device's internal processes, helping to identify if a device is stuck in a particular state or if a component (like an encoder) is not being evaluated correctly.
- Troubleshooting Guidance: The manual provides specific actions or comments for various display messages and errors, guiding users through the troubleshooting process (e.g., "Check the mains connection" for DC link voltage missing, or "Remove the keypad and plug it back in" for keypad connection error).
- Copyright and Recycling Information: The manual includes copyright notices and information on recycling, reprocessing, and reuse, reflecting SEW-EURODRIVE's commitment to sustainability and proper product lifecycle management.
